Hi
When I receive an LFD email the subject is something like

SSH login alert for user root from xxx.xxx.xxx.xxx (FR/France/user.domain.com)

But that server connecting is NOT in France. It is in Canada. And when I check the IP is clearly publicly in Canada.

Which service determines this information? Where does FR/France come from?

Thanks!

We have been using CSF on cPanel quite successfully for years and over the last couple of years, we have started using them on Virtualmin/Webmin servers as well. The difference we see is that while CSF is very well optimized for cPanel with lot of additional custom configuration like monitoring unwanted scripts, monitoring exim login attempts and blocking them if necessary, monitoring service...

Hello,

my /usr/local/cpanel/logs/login_log is full of failed whm login attempts from ip addresses in verry strange countrys but it looks like the attackers know the defending mechanism against this type of attack because they stop after two failed attempts and a few hours hours later they try again.

I know this would be a working as designed status as my LF_CPANEL is set to 5 so it only...

Is the intended behavior that csf /lfd will only email upon the first WHM root access from the same IP within so many hours?

I'm trying to figure out why lfd only sent one email WHM/Cpanel root access alert when I logged in and out and then in again a few times to WHM. The cpanel login_log shows all three WHM logins, but lfd only emailed once and only logged the first whm login to...

Hi
I have a recurring issue on my 2 cpanel/whm controlled vps servers CENTOS 7.9 kvm v94.0.3 .
I have installed csf and lfd as per 'the book' BUT, if I leave service csf enabled the load average gradually ramps up to a huge and non resposive value (I have seen 30 30 30!! - that took some recovery from)
However as soon as I 'systemctl stop csf' the load averages rapidly drop to their usual values...

whoops... silly error. I was placing my ignore commands under IP Blocking rather than process blocking ... completely missed the drop-down list of ignore options.

I try to find solution but I could not find anything that works for me...

Hi there. Lately I was getting a lot of errors like
*Error* pid mismatch or missing, at line 1160
daemon stopped
This error is caused by trying to block some IP address, which triggered csf of lfd rule few times in a row. After that csf is disabled, but it was reenabled by cron job, which monitors services state

This is from lfd.pl (including line 1160, where an error is triggered)
while (1)...

Hello,

we have a server that needs to be able to access mysql with the root user.

We have blocked port 3306 globally.

And allowed the authorized IP in csf.allow with the following format:
tcp|in|d=3306|s=x.x.x.x

We check that it works fine, but we have found a strange log:

cat /var/log/mysqld.log | grep Access denied

I try to set restriction to user and not general SMTP restriction.
As I understand SMTP_BLOCK should be ON and additional per user

Is this correct?

Hello,
I am new using ConfigServer security & firewall and can use some guidance.

I am trying to set it up so that I receive alerts when certain actions take place for example when the server load is high.

My first question is can alerts only be sent via email? Or are there other ways of sending alerts such as SMS or post to url?

Can you point out where in CSF you specify these settings, for...
